WALTER J JOHNSON AND ARTHUR L. JOHNSON, OF CHICAGO, ILLINOIS.

To all whom it may concern:

Be it known that we, WALTER J. JOHNSON and ARTHUR L. JOHNSON, citizensof the United States, residing at Chicago, in the county of Cook andState of Illinois,.have invented a certain new and useful Improvement inChair-Seats, of which the following is a specification.

Our invention relates to chair seats, more particularly of the typewherein a portion of the seat is removable. v

One of the objects of the invention is to provide a construction'inwhich the front rail of the removable or slip seat constitutes theforemost rail of the chair.

Another object is to provide a seat which may be removed from the seatframe without raising the seat, but merely slipping it in a forwarddirection.

.An'other object is to provide in a seat of this character a frontextending entirel or approximately across the entire width 0 the chair.

A fourth object is to provide a slip seat lending itself particularly toa so-called saddle shape.

Fifth, it is our object to produce a con removed and a portion of thepadding or.

lining being also removed to better reveal I the construction of theparts. Fig. 2 is a top view of the support with the seat removed. Fig. 3is a vertical section on the line 3, -3 Fig. 1, and Fig. 4 is a verticalsection on the line 4, 4 Fig. 1.

Similar numerals refer to similar parts throughout the several views.

Referrin to the drawings in which'a preferred em odiment of theinvention is shown, the stationary support for the seat consists of afront rail 1, side rails 2, 2, and a back rail 3. Over this support lie'two side rails 4,4 and a back rail 5, which are set back somewhat fromthe inner margins of .the parts 2 and 3 to afford a supporting ledge orshoulder for the seat. Said rails 4 and 5 rise preferably to the heightof the 'ence do not reach Specification of Letters ratent. Patented une27, 1916 Application filed March 17, 1915. Serial No. 14,888. I

slip seat and form stops or abutmentsthere for. The major portion of thefront remains uncovered. In consequencefitw be said that the rails 4, 4,5 are opn'atgt front. Theoretically these parts ,might fbe I I carvedfrom a single piece, but as a practical matter of manufacture thedifi'erentjelements referred to should be made of separate pieces ofwood, glued or otherwise rigidly secured together. The side rails 4 arecurved outwardly at their forward ends and by preferquite to the forwardedge of the front rail.

The preferred arrangement of the parts is clearly shown in Fig. 2. Theparts mentioned form a permanent and stationary part of the chair, andas the legs, back, and arms of the chair may assume many differentforms, and as such parts are well lmown, it isthought unnecessaryto'illustrate them.

The slip seat comprises a frame having a' front rail 7,'two side rails8, 8 "and a' back rail 9. These parts are preferably made of four piecesof wood suitably joined to ether. Theyconform in general to the out ineof the stationary support, the front rail 7 restingupon the front rail 1and the side and back rails resting upon the exposed marginal edges ofthe side rails 2 and back rail 3 respect1vely.' The forward edge of thefront rail 7 comes flush or somewhat in front of the forward edge of thefront rail 1 and at the ends swings out so as to come in front of theforward ends of the side rails 4. Thus the slip seat presents acontinuous front, entirely across the width of the chair.

The front rail 7 when viewed in cross-section, as on the line 3, 3, Fig.1 is rounded with the top of the rails 4, 5 and the inner edgesinclining downward as shown.

The area bounded by the rails 7, 8 and 9 is covered by cane-seating 11,fastened in any suitable manner to the rails of the slip seat.-Overlying this cane-seating is a what we claim as new and desire tosecure 55 leather cover 12, and by preference a lining 13 of felt orother suitable material is inter- .posed between the cane-seating andthe cover. The cover extends around over the front edge of the frontrail 7 and secured along the. under edge, covering the entire topsurface and sides of the slip seat, and thereby imparting a finished ap-.place the fastening of the cover to th pearance thereto. When the slipseatfis 1n frame workis not apparent.

We call particular attentlon, in

addition .to the general features of construction, to

v renders it possible to employ cane seating,

. upon a saddle. shaped chair seat.

' 1 front end ofv the center ridge 7* is comthe presence of the tongue7. 'lhis tongue The I paratively high, much higher than theelevation ofthe central portion ofthe seating. By thus providing the tongue it ispossible to avoid a sharp drop "at the inner edge of the front railwhich would have a tendency to'very soon out the cane. Withourconleather coveringis also protected, for the.

struction it is possible to taper oh the ridge "to a point flush withorbelow the plane of the caning. By protecting the cane, the

cover cooperates with the caning in supporting the weight of the personusing the chair.

As a result of the construction shown, the

leather cover is brought to the. fore-frontof the seat under the-kneesof the user and this covered front extends throughout the entire widthof the chair. This avoids any ridges or unevenness, such as isfrequently found in chairs in which the stationary front rail comes infront of the removable seat. shaped it is comfortable, especiallyin'view ofthe fact that instead of being solid wood as saddle seatsusually are, it is madeof necessary to reach under-and push up frombeneath, a draw back that is avoided in a chair of our construction.

Having thus described our -1nvention,

Furthermore, as the seat is saddle.

by Letters Patent, is

1; In a chair, the combination of a stationary support having marginalstrips rising therefrom at the sides and back, said strips at the sidesterminating short of the frontedge of said support; and a slip seatfitting within the marginal strips on the stationary support andextending to a point in front of them, and extending, across the front,approximately to the outer edges of the side marginal strips.

2. A chair having a stationary support having a front rail, side railsand a back rail rising above the level'of said support, the ends of theside rails being rounded outward at the front ends; and a slip seatresting upon said support and abutting said ralls to be held laterallythereby, the top of the seat being substantially flush with the top ofthe side and back rails of the support, and said seat having a frontrail having laterally extending wings at the ends rounding outwardaround the front ends of the side rails of the support and terminating.substantially at the outside edges of saidside rails, the spread of thewings being substantially equal to the greatest width of said support.

3. In a chair, a slip seat consisting of a frame having a front rail,side rails and a back rail, and a flexible covering stretched front railhaving a center ridge which tapers down onto said tongue.

4:. In a chair, a slip'seat consisting of a frame having a front rail,side rails and a back rail and a flexible covering stretched over saidframe, the front rail having a center ridge, and a tongue projectinginwardly toward the center of the frame at 7 least half way to saidcenter, said tongue carrying the ridge down as far as the level of theadjacent inner edges of the side rails.
